What is demurrage and detention?

In trucking, detention charges compensate drivers and carriers for unreasonable delays during loading or unloading beyond standard free time allowances (typically 2 hours).

In container shipping, demurrage applies to container storage within the port terminal beyond free days, while detention applies to container retention outside the terminal.

Why accurate demurrage calculation matters

Unanticipated demurrage fees can dramatically erode shipment profitability. Early estimation helps logistics teams budget contingencies and contest incorrect carrier invoices.

Frequently Asked Questions

How is road transport detention calculated?

Subtract agreed contract free time (e.g. 2 hours) from total dwell time, then multiply remaining hours by the agreed hourly detention rate.

What is the key difference between demurrage and detention?

Demurrage covers on-terminal equipment dwell time, whereas detention covers off-terminal container usage until equipment is gated in empty.

Can demurrage fees be waived?

Carriers may waive or reduce fees in cases of verified customs administrative delays or documented terminal equipment malfunction, depending on charterparty terms.
